Answer:
A: Volume and Amount of Gas
B: 3
C: 4
D: 4
E: 3
F: Gay-Lussac's Law
G: Directly Proportional Relationship
Explanation:
A: When looking at the information given, each container contains the same amount of particles and the size of the container is stated to be the same. Therefore, these two variables remain constant.
B: KE is determined by the temperature, which means the container with particles at the highest temperature has the highest amount of KE. This would be container 3.
C: The container with the lowest temperature is 4.
D: The container with the lowest pressure is 4 because a lower temperature means lower pressure.
E: The container with the highest temperature has the highest pressure because the particles are moving faster, meaning more pressure exerted against the container.
F: Gay Lussac's Law because this law shows the relationship between pressure and temperature.
G: This is a directly proportional relationship because as temperature increases, pressure increases. As temperature decreases, pressure decreases.
Answer: gradual increase in temperature of ice from −15°C to 0°C, holding at 0°C as ice melts to water
Explanation: The heat used to convert solid to liquid is gained by molecules to gain kinetic energy and thus the molecules start moving faster and the temperature increases.
But as the melting point is approached i.e. , the temperature remains constant as now the heat given is used to break the inter molecular forces and thus is not reflected in terms of temperature increase. This hidden heat is called as latent heat.
The temperature remains constant till the phase change is complete.
The answer to this question would be: 11.5 grams
The molecular mass of hydrogen is 1, oxygen is 16 and carbon is 12. Then the molecular mass of CH4O would be: 12 + 4(1) + 16= 32.
To find the hydrogen mass, you just need to divide the hydrogen with total mass, resulting in the mass ratio of hydrogen to the compound. Then the amount of hydrogen inside 92 gram of CH4O are: 92grams * (4/32)= 11.5 grams
